System requirements and features

Before we continue, let’s talk about the system requirements and how it works. For starters, it will only work on a Windows-based machine. The main machine must be running Windows 10, Windows 8.1, or Windows 7.

Secondary machines can run any of the following operating systems and devices:

  • Windows 10
  • Windows 8.1
  • Windows 7
  • Android (version 4.1 or later)
  • iOS (version 9.3 or later)
  • An HTML 5 web browser (Chrome (>16), Safari (>5.1), Internet Explorer (>10), Opera (>27))
  • Windows Phone (Windows Phone 10/8.1)
  • Windows Surface, Tablet, Laptop and PC (Windows 10, 8.1, 8, 7, Vista, XP)
  • Mac OS X)
  • Linux PC and Laptop

You must be running a local area network (LAN) that supports TCP/IP v4. The way it works is that the Spacedesk software on the primary machine captures the screen content and then compresses it by transmitting it to the Spacedesk software over the LAN on the secondary device.

A really cool feature of this setup is that this software will allow you to mirror your desktop or extend that desktop to other devices. When in extended mode, you can drag windows from one screen to another.
